Zexuan Demountable Derrick-Supported Flares represent the pinnacle of operational maintenance flexibility. Engineered with a specialized internal guiding track and winch system, this design allows the flare tip and individual riser sections to be lowered to ground level for servicing without requiring large cranes or a complete plant shutdown.
Key Technical Advantages
Zero-Crane Maintenance: Flare tips and risers are lowered safely to grade using integrated winches, eliminating massive mobilization costs for heavy cranes.
Uninterrupted Plant Production: For multi-riser configurations, one riser can be lowered for service while the other risers remain operational.
Enhanced Operator Safety: All critical maintenance tasks are performed comfortably at ground level, reducing high-altitude work risks.
Technical Specifications
- Lifting Mechanism: Integrated heavy-duty electric/hydraulic winches and high-tensile guide cables.
- Lowering Capacity: Full riser assembly or modular tip-only sections.
- Structural Coating: Hot-dip galvanized or specialized offshore epoxy coatings.
Target Applications
- Continuous-Operation Petrochemical Facilities (No-Shutdown policies)
- Remote Offshore Platforms & Island Refineries (Where heavy cranes are unavailable)
- Highly Corrosive Environments requiring frequent tip inspections
